Background technology
Capacitor core is a kind of energy-storage travelling wave tube, using its charge and discharge in transient process, it can be achieved that interference signal
Bypass absorbs.
But actual capacitance fuse is unlikely to be purely capacitive property, it also includes resistance and inductance, equivalent circuit such as Fig. 1 institutes
Show.
Due to the various inductance effect in actual capacitance, there are highest effective frequencies.
When interference signal frequency is more than fe, capacitor core inhibits overvoltage effect to significantly reduce in perception.Occur in power grid
Switching overvoltage or spike have that rate of voltage rise is high, amplitude is big, pulse duration short feature, frequency spectrum
Be distributed as discrete be distributed within the scope of broad frequency band.Therefore such interference, effect is inhibited to pay no attention to conventional capacitive fuse
Think.
